Improve your fluid intelligence with BetterBrain.

Fluid intelligence is the ability to reason and solve new problems independently of previously acquired knowledge. With BetterBrain you practice challenging memory tasks where you have to remember simultaneously audio and visual events. A scientific study has shown a positive effect of this training on the fluid intelligence of a test group.

The memory task you need to practice is the 2-back task where you must remember the letter you heard two steps back in the past and simultaneously the position of a square on a three by three grid.

BetterBrain features multiple user controlled settings such as two additional training tasks (audio position, color change, form) and adaptive difficulty control: Once you make sufficient progress, you may work on the more challenging 3-back task and if you make too many mistakes, the level will be reduced. Another advantage of BetterBrain is the possibility to practice dual channel memory tasks which are either fully audio or fully visual.

You can also export via email or iTunes a complete log file of your training sessions for later analysis.
